The fund seeks a favorable long-term total return, mainly through capital appreciation, primarily from equity securities of medium-sized domestic companies. It normally invests at least 80% of its assets in mid-cap equity securities. The fund's management team looks for companies it believes have prospects for strong earnings or sales growth. Management focuses on equity securities of companies that it believes may represent high growth industries or rapidly evolving areas of the economy, that have distinctive products or services and that are growing faster than the overall equity market. The fund may invest up to 20% of its assets in foreign securities.

Performance Returns

Average annual total return is a hypothetical rate of return that, if achieved annually, would have produced the same cumulative total return if performance had been constant over the entire period. Average annual total returns smooth out variation in performance; they are not the same as actual year-by-year results. Also, it is the average annual profit or loss realized by an investment at the end of a specified calendar period, stated as the percentage gained or lost per dollar invested.

As of 02/28/2015

The performance data quoted represents past performance, and is no guarantee of future results. Your returns and the principal value of your investment will fluctuate so that your accumulation units or shares, when redeemed, may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted above. Performance may reflect waivers or reimbursements of certain expenses. Absent these waivers or reimbursement arrangements, performance results would have been lower. Since Inception performance shown is cumulative for funds that have less than one year of performance history. For investments with exceptional performance, please note that performance fluctuates and currently may be lower than noted here.

Morningstar is an independent service that rates mutual funds and variable annuities.

For each fund/account with at least a three-year history, Morningstar calculates a Morningstar Rating™ based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's/account's monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Where applicable, Morningstar's performance rankings are based on linked performance that considers the differences in expense ratios, while actual performance data shown does not reflect such differences.

The top 10 percent of funds/accounts in a category receive five stars, the next 22.5 percent receive four stars, and the next 35 percent receive three stars, the next 22.5 percent receive two stars and the bottom 10 percent receive one star. (Each share class is counted as a fraction of one fund/account within this scale and rated separately, which may cause slight variations in the distribution percentages.) Morningstar proprietary ratings on U.S.-domiciled funds/accounts reflect historical risk-adjusted performance, are subject to change every month. They are derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar Rating metrics. Please note, Morningstar now rates group variable annuities within the open-end mutual fund universe.

Investment Risk

Investment risk is usually related to the performance of an investment—riskier investments offer potentially higher returns—but are more volatile in the short-term. Beta (past price fluctuations), R-Squared (performance against benchmark index), and Standard Deviation (past volatility) are all used to calculate the degree of risk associated with individual investments.

Level of risk is defined using the 3 Year Standard Deviation of the Investment.
